Obviously, there is no sunlight energy for light dependent reactions to occur while calvin cycle AKA light independent phase does not require light as it uses energy in the form of ATP and the NADPH to form sugars

What two types of reactions occur during photosynthesis?

The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.


What two reactions occur in photosynthesis?

There are three carbon dioxide, water, and sunlight.


What happens during each of the two stages of photosynthesis?

These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.


True or false The light reactions of photosynthesis can occur only under light conditions and the dark reactions can occur only during the dark hours?

false; dark reaction is independent of light

What Will Most Likely Happen To a Plant That Does Not Does Not Receive Any Water?

The light-dependent reactions will not occur.


What is the difference between the light dependent reactions and the light independent reactions?

light dependent reactions only occur in light this means thier reations increases with light intensity while light independent can occur in the dark


Is carbon dioxide taken into the chloroplast during light dependent reactions?

No, carbon dioxide is not taken into the chloroplast during the light-dependent reactions. The light-dependent reactions occur in the thylakoid membrane of the chloroplast and involve the conversion of light energy into chemical energy in the form of ATP and NADPH. Carbon dioxide is actually taken in during the light-independent reactions, also known as the Calvin cycle or dark reactions, which occur in the stroma of the chloroplast.


In what organelle do light reactions occur in plants?

Both light and dark reactions occur in the chloroplasts of cells. More specifically light reactions take places in the thylakoid, dark in the stroma.


Where do the light reactions occur in the leaf?

Chloroplasts


How are the dark reactions that occur in plants dependent on the light-reactions?

The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.
